Intervention / Treatment
Detailed Description
Preliminary evidence suggests that low-fat, vegetarian diets and certain nutritional supplements can help reduce pain and also reduce the need for pain medications for some people. The investigators will ask about 100 people to participate. All of them will get a low-fat, vegan diet and a nutritional supplement (mixture of omega-3 oils and vitamin E or a placebo), although some will get the diet first, and others will get the supplement first. This order in which they will get the diet and the supplement will be determined randomly, that is, by chance (like the toss of a coin). The principal measures are pain as measured by Visual Analog Scale (VAS)and the change in migraines frequency.
Mood change will be measured using the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R), and the Beck Depression Inventory II (BDI-II).
